University of Calgary participation in CCAT CHAI development

Cerro Chajnantor Atacama Telescope (CCAT) will be a next-generation submillimeter telescope performing a broad range of submillimeter wave astronomical observations. Currently, the development of CCAT is undertaken by universities from USA, Canada, and Germany with others expressing interest in the project. This paper gives a brief overview of CCAT and its first-light Heterodyne Array Instrument (CHAI). The development of a CHAI receiver conducted at the University of Calgary is discussed.
